jair101 Posted June 14, 2016 Share Posted June 14, 2016 My 3.4.x installation was happily ticking until the last couple of weeks when I have started noticing delay when post submitting and liking content. - Loading and reading - no problems - Editing - no problems - Submitting in new threads - usually fast - Submitting and liking in old threads - slow I felt that it is somehow related to notifications, because otherwise I do not understand why submitting is slow, but edit is fast. I assumed it is because submitting needs to send a notification to all thread subscribers and thats a lot of people, especially in the large topics. I tried to limit the stored amount of notifications, but it didn't help. Tried locking large topics, didn't help either. Occasionally I get double posting too, signal that things aren't running smoothly. The only configuration change I made recently was switching from Mandrill to Sparkpost, no new plugins, no anything. Configuration is Apache/Mysql, around 150k posts and 50 members + 150 guests online on average. The community is running on 2GB, 2xcore VPS and it is the only website on this vps. Any ideas?

Rhett Posted June 14, 2016 Share Posted June 14, 2016 Check your email config in the acp, if it's using smtp and is performing slow, it could be related. Link to comment Share on other sites More sharing options...
EricT Posted June 15, 2016 Share Posted June 15, 2016 I have the same issue since a few days. I am using sparkpost EDIT : lol here too (about 4 seconds to post this reply) (and a few milliseconds to add content to this reply, next) Link to comment Share on other sites More sharing options...
Marc Stridgen Posted June 15, 2016 Share Posted June 15, 2016 Seems a bit odd that you are seeing this in more than one place. This would point more to it being on your side rather than that of the server. Have not seen any issues on the site here whilst I have been posting. Is this something you experienced just the one on this site, or something you are experiencing consistantly? Link to comment Share on other sites More sharing options...
EricT Posted June 15, 2016 Share Posted June 15, 2016 I am not experiencing it consistantly. What I am sure : since a few days (at work or at home), sometimes when I post some content on forum, the "Submit Reply" goes to "Saving" button and stay saving during a few seconds. I didn't noticed that in past. I will ask my community users to see if they have the same problem. Link to comment Share on other sites More sharing options...
ABGenc Posted June 15, 2016 Share Posted June 15, 2016 I have had the same problem for a few days. Thanks to @RevengeFNF's advice on taking a look at SMTP config as @Rhett suggested . I have found out that for those topics which have several followers posting a new reply would mean almost 10 seconds or even more waiting. You can check how fast you can send Test Mail on ACP to yourself. If that takes a lot of time too than you have the same problem as I did. You can choose to disable email notificaiton for following cases so that posting on old threads become easier. New content for things I follow Someone comments on something I follow Than check your email logs and SPAM config. There might be a bottleneck or an option slowing SMTP connections down..

How can I do that globally? I thought this is per user setting. I will sign up for sendgrid tonight, just as a test to see if it solves the issue.

You may need to set Member can edit setting to disable Link to comment Share on other sites More sharing options...

You may need to set Member can edit setting to disable Yeah, but I believe the setting stays the same for all members before the change, so I won't be able to see the results immediately. Anyway, I switched to Sendgrid from Sparkpost and can confirm that there is a notable improvement. I am waiting 24h and more reports from my members to confirm, but I believe this was the issue.

There are two way you can disable the setting. You can uncheck email and set "Member can edit?" option to disable You can check email for "Disabled Notification method" Both disable email notification globally Link to comment Share on other sites More sharing options...
jair101 Posted June 16, 2016 Author Share Posted June 16, 2016 I can confirm that at least in my case it was Sparkpost causing the problems. There is a slight lag with sendgrid too, but at most a second, while with sparkpost delay was often up to 10 seconds. Apparently this is an inefficiency of the SMTP relay model and if using Sparkpost as integrated in 4.0 it might be better, YMMV. Link to comment Share on other sites More sharing options...
Summit360 Posted January 23, 2017 Share Posted January 23, 2017 Thread Necromancer - Thanks for this... The one bit I could not easily test before migrating was email. Of course I did the migration, all went well enough... massive posting delays. The only difference I'm using Amazon SES, so smtp. The upgrade must of jiggled a few settings, or rather made them work better Got it sussed and this helped eliminate the last gremlins.. not ideal. People will want there email notifications.

AlexWebsites Posted March 29, 2017 Share Posted March 29, 2017 I'm noticing the same and have sparkpost enabled. In one of my topics i tested I have 57 followers and it took 12 seconds to post the reply. If that's the cause, It would be better to load the reply and in the background send the notifications. Tested by switching to php mail and posted in 5 secs same topic with 57 followers and immediately with another topic that only has 2 followers. has to be the 3rd party email causing slowness.
